Struct PyASCIIObject

Source
#[repr(C)]
pub struct PyASCIIObject { pub ob_base: PyObject, pub length: isize, pub hash: isize, pub state: u32, pub wstr: *mut i32, }

Fields§

§ob_base: PyObject§length: isize§hash: isize§state: u32

A bit field with various properties.

Rust doesn’t expose bitfields. So we have accessor functions for retrieving values.

unsigned int interned:2; // SSTATE_* constants. unsigned int kind:3; // PyUnicode_*_KIND constants. unsigned int compact:1; unsigned int ascii:1; unsigned int ready:1; unsigned int :24;

§wstr: *mut i32

Implementations§

Source§

impl PyASCIIObject

Interacting with the bitfield is not actually well-defined, so we mark these APIs unsafe.

Source

pub unsafe fn interned(&self) -> u32

Get the interned field of the PyASCIIObject state bitfield.

Returns one of: SSTATE_NOT_INTERNED, SSTATE_INTERNED_MORTAL, SSTATE_INTERNED_IMMORTAL, or [SSTATE_INTERNED_IMMORTAL_STATIC].

Source

pub unsafe fn set_interned(&mut self, val: u32)

Set the interned field of the PyASCIIObject state bitfield.

Calling this function with an argument that is not SSTATE_NOT_INTERNED, SSTATE_INTERNED_MORTAL, SSTATE_INTERNED_IMMORTAL, or [SSTATE_INTERNED_IMMORTAL_STATIC] is invalid.

Source

pub unsafe fn kind(&self) -> u32

Get the kind field of the PyASCIIObject state bitfield.

Returns one of: PyUnicode_WCHAR_KIND, PyUnicode_1BYTE_KIND, PyUnicode_2BYTE_KIND, or PyUnicode_4BYTE_KIND.

Source

pub unsafe fn set_kind(&mut self, val: u32)

Set the kind field of the PyASCIIObject state bitfield.

Calling this function with an argument that is not PyUnicode_WCHAR_KIND, PyUnicode_1BYTE_KIND, PyUnicode_2BYTE_KIND, or PyUnicode_4BYTE_KIND is invalid.

Source

pub unsafe fn compact(&self) -> u32

Get the compact field of the PyASCIIObject state bitfield.

Returns either 0 or 1.

Source

pub unsafe fn set_compact(&mut self, val: u32)

Set the compact flag of the PyASCIIObject state bitfield.

Calling this function with an argument that is neither 0 nor 1 is invalid.

Source

pub unsafe fn ascii(&self) -> u32

Get the ascii field of the PyASCIIObject state bitfield.

Returns either 0 or 1.

Source

pub unsafe fn set_ascii(&mut self, val: u32)

Set the ascii flag of the PyASCIIObject state bitfield.

Calling this function with an argument that is neither 0 nor 1 is invalid.

Source

pub unsafe fn ready(&self) -> u32

Get the ready field of the PyASCIIObject state bitfield.

Returns either 0 or 1.

Source

pub unsafe fn set_ready(&mut self, val: u32)

Set the ready flag of the PyASCIIObject state bitfield.

Calling this function with an argument that is neither 0 nor 1 is invalid.
